    1. gravity pulls rocks towards it because of gravitational pull

      Delete
  3. gravity rips everything down

    ReplyDelete
  4. Gravity acts as a force of erosion because when things get wet the gravity makes it slide down. This happens with rockfalls as well.

  5. when rocks cant hold weight and the weight of the rocks and it breaks and falls (smart person answer)

    ReplyDelete
  6. gravity affects erosion because if there's a cluster of rocks on a hill the force of gravity will start pulling them down.

    ReplyDelete
  7. Gravity acts as an erosional force by creating avalanches and land slides. And that's how gravity acts as an erosional force.

  8. Things like mountains get smaller because Earths gravitational pull is forcing it towards Earths center.

  9. if a tree is on the ege of cliff it will creep off the cliff.

  10. gravity is a pressure that pulls down and keeps pushing down thats why the rock crumble from there wait and gravity

    ReplyDelete
  11. the sediment comes apart and falls out.

    ReplyDelete
  12. Like a cliff fall down because of creep.

    ReplyDelete
  13. Mass movement is a process that moves rock and sediments.

    ReplyDelete
  14. the force pushes the rocks down over time.

    ReplyDelete
  15. When it rains and there is no vegetation then it gravity pulling on all of the sand and dirt can cause a landslide and everything will fall down with the landslide.

    ReplyDelete
  16. Over time it will push things downslope.

    ReplyDelete
  17. Gravity makes the rock fall when the force lets go that's when the action starts.

  19. when there is an earthquake and there is a huge hill with rocks on it there more than 50 percent there going to fall and possibly could kill someone it can be very dangerous and that is y i like Maine because there is not a lot of earth quakes in Maine.

  20. It like your beach house from yesterday It fell down from the creep.

    ReplyDelete
  21. mudslides can dig up the rock thats why they fall every ware

    ReplyDelete
  22. rockfalls are from gravity pulls the rock down.

    ReplyDelete
  23. Gravity acts as a erosional force by pulling things towards the Earth center.

    ReplyDelete
  24. Gravity is the force behind precipitation in the water cycle. Rain, snow, and other forms of falling water are carried to Earth by gravity. There, the liquid water can wash away materials away. Snow can accumulate and melt and do the same thing. Snow can also freeze, and then become a moving block of ice, or a glacier. We all know glaciers can move massive amounts of rock. We also know that gravity directly acts to pull down geologic structures, like cliffs or even mountain slides. Loose rocks or earth is dragged down from higher points all the time, and it might be one or two chunks of material, or a landslide. Even the great Spires in Monument Valley succumb to gravity's pull.

  25. GRAVITY PULLS STUFF DOWN LIKE IN A ROCK SLIDE

    ReplyDelete
  26. because gravity pushes things down and when it has enough gravitational pull then it pushes the rock down and makes a rock slide

    ReplyDelete
  27. Gravity causes erosion because it pulls everything towards the center of the earth.

    ReplyDelete
  28. it acts like an erosional force to keep us on the ground so we don't fly in space and die

    ReplyDelete
  29. it can make mudslides, earthquakes, and it can cause avalanches.

    ReplyDelete
  30. Gravity is like a erosional force it keeps stuff on the ground so it pretty much pulls stuff down.

    ReplyDelete
  31. During time or over time it will push thing down slope

    ReplyDelete
  32. Gravity is the strongest force on earth it could destroy any thing it wanted to like make a rock slide or an avalanche.

    ReplyDelete
  33. gravity can move things if its strong enough and if its so strong it can cause things like rock slides in the picture.

    ReplyDelete
  34. Gravity will pull the ground down and it will crush the ground in a way

    ReplyDelete
  35. Gravity makes a rock slide

  38. Gravity can cause mudslides, earthquakes, and it can cause avalanches. If you were an inanimate object and could not stop from moving gravity would cause you to roll down hill too.

  41. Gravity causes rock slides because it pulls the rocks closer to the earths center.

    ReplyDelete
  42. and wind water and ice does that

    ReplyDelete
  43. Gravity pulls objects toward Earth's center. Gravity will pull weathered objects on a slope to a lower position. Because of this, the pull of gravity is responsible for landslides, slump, mudslides, and creep.

    ReplyDelete
  44. Gravity is an erosional force because of mass movement,gravity creates landslides because it can't hold up the base anymore, making gravity take down almost the entire piece of land until it can hold it up again.

    ReplyDelete
  45. When rocks tumble because of the gravitational force, they crash into each other chipping bits of the rock and mineral off. If there was no gravity rocks wouldn't be sharp or scratchy they would be smooth and there would be no dents or cracks on them.

  50. Gravity moves materials down slope like ice or a glaicer

    ReplyDelete
  51. It push is the plates when the earth moves and creates earthquakes,witch goes along with weather like rain,snow,ice,heat,wind,ect. so that being said,you get erosions.

    ReplyDelete
  52. gravity makes the mountains smaller because mountains are tall and the gravity makes it in to big rocks.

    ReplyDelete
  53. Gravity makes rocks fall when mountains get weathered. i think

    ReplyDelete
  54. gravity makes the moutains smaller because mountains are tall and the gravity makes it in to big rocks

  58. Gravity acts as an erosional force when a mountain over time with the wind knocks over the top of the mountain, the gravity brings it downward and smashes/ damages other things on the ground.

    ReplyDelete
  59. Gravity causes the rock to fall on the road creating a rockslide which removes the rock from the mountain and blocks the road.

    ReplyDelete
  60. gravity makes pieces of rocks fall of the mountains

    ReplyDelete
  61. gravity makes mountains into big rock

    ReplyDelete
  62. Slomp/slop

  63. Gravity can cause mud slide were a mountain down or anything like that gravity can move materials down hills mountains and slopes.

    ReplyDelete
  64. Gravity makes things stay on the ground.

    ReplyDelete
  65. If something starts to slump then gravity helps to bring it down faster and if there wasn't to be gravity then it wouldn't slump at all

    ReplyDelete
  66. gravity acts as an erosional force because when it makes the rocks and stuff stay on the ground it interfres with the chemical balances

    ReplyDelete
  67. Let's say there is a huge mountain with ledges and boulders hanging on it. Gravity is going to push down on the mountain and one rock might move, then that causes another, and another, and another to move. Eventually enough force on the rocks will push larger rocks off the ledge of the mountain. This causes and avalanche, or a rock slide. It will roll down the mountain, piking up more rocks as it goes. At the bottom of the mountain, the rocks build up and create more mountains and hills.

    ReplyDelete
  68. Gravity acts as an erosional force because when rocks are unstable gravirt might pull them down, and in the process pulling more rocks down, and causing a rock slide.

  69. When it rains there is no vegetation. Gravity pulls on all of the sand and dirt. This can cause a landslide. In a landslide everything will fall down with the landslide.

    ReplyDelete
  70. Gravity is a force that pulls stuff down so gravity causes landslides.

  71. When it rains there is no vegetation. Gravity pulls on all of the sand and dirt. This can cause a landslide. In a landslide everything will fall down with the landslide.

    ReplyDelete
  72. when the rain comes down the isn't any vegetation. then gravity pulls down all the dirt and sand. then it will cause a land slide and in a landslide everything will go down with the land slide.

    ReplyDelete
  73. gravity pulls the sand and dirt down if it's on a mountain or if its high up or in the air.

    ReplyDelete
  74. is when rocks fall on a rail road track

    ReplyDelete
  75. Gravity force is something that has the ability to pull something to the ground.

    ReplyDelete
  76. Gravity is a force that keeps objects from floating away. It can also pull objects down to earth like rocks and sand.

    ReplyDelete
  77. When it rains, there is no vegetation. Gravity's job is to pull everything toward the Earth's center. So that causes gravity to pull the loose dirt and sand after it has rained. When that happens it can cause a landslide, mudslide, etc.

    ReplyDelete
  78. Gravity is a bully and pulls land that has no trees or plants and that are on a slope like that picture at the top.

    ReplyDelete
  79. Gravity can cause landslides, because gravity pulls the rocks down after one big rock falls. When one rock falls it starts a chain reaction after gravity pulls the other rocks down.

    ReplyDelete
  80. when something is already eroded naturally gravity acts and moves the eroded object.like if a mountain is already weathered and eroded and is lose it will naturally fall as a result of gravity.

    ReplyDelete
  81. If there is no rain there is no trees, plants, and other vegetation stuff in the world. Then the gravity will pull all of the sand and dirt. These things can cause a landslide. If things are in the middle of a landslide then everything will fall with the landslide.

    ReplyDelete
  82. When it rains their is no vegetation. On a steep slope by the highway that had loose rocks, gravity would pull the rocks tumbling down then slope and into the path of the highway, which would be called a landslide. Or if a garden is on a hill, then people put on the sprinkler then it could cause mud to go down the hill, which is called a mudslide.

    ReplyDelete
  83. Gravity can effect erosional force because gravity can pull anything down to earth. Gravity can pull down mountains, and can even make landslides.

    ReplyDelete
  84. for example when there is a avelanch gravity takes whatever is falling and pushes it towards the ground until it hits a solid surface

    ReplyDelete
  85. Gravity acts as an erosional force and creates avalanches and land slides. That is how gravity acts as an erosional force. Well that's what happens when there's no vegetation to help the dirt and gravel be compact.

    ReplyDelete
  86. Gravity moves things down slope like ice or a glacier.

    ReplyDelete
  87. Gravity is an erosional force because of mass movement,gravity creates landslides because it can't hold up the base anymore, making gravity take down almost the entire piece of land until it can hold it up again.

  88. Gravity acts as an erosional force by gravitating stuff.

    ReplyDelete
  89. They all cause damage, the they cause rock slides and avalanches.
